Not really, especially in blacksmithing terms. Iron and steel are different on a molecular level. Steel has iron but its not iron in itself. Same way bronze has copper but its incorrect to call it copper.

Leaf springs are great for swords due to its specific carbon content, they make very tough blades. the best way to grind a fuller is with a narrow belt sander you can pull it off with an angle grinder but its very tricky

Hey i have some experience. Tempering a sword varies depending on how big it is, it has to be done after the initial heat treatment. You can use a regular oven if the blade is small enough or else you'd need a tempering oven. You'd heat it at 400-450 Fahrenheit for two to four hours.rust needs to be ground out before you start forging or else you can run into some problems,starting with knives is always a good start to blacksmithing,
